2. INSTALLATION AND START UP
2.6 When switching power on for the first time
Before starting operation, check the following:
(1) Wiring
(a) Check that the control circuit power cable, main circuit power cable and servo motor power cable
are fabricated properly.
(b) Check that the control circuit power cable is connected to the CNP1B connector and the main
circuit power cable is connected to the CNP3 connector.
(c) Check that the servo motor power cable is connected to the drive unit CNP2 connector.
(d) The earth terminal of the servo motor is connected to the PE terminal of the drive unit. Also check
that the drive unit is screwed to the base unit securely.
(e) When using the regenerative brake option, check that the cable using twisted wires is fabricated
properly and it is connected to the CNP1A connector properly.
(f) 24VDC or higher voltages are not applied to the pins of connector CN3.
(g) SD and SG of connector CN3 are not shorted.
(h) The wiring cables are free from excessive force.
(i) CN1A should be connected with the bus cable connected to the servo system controller or preceding
axis servo amplifier, and CN1B should connected with the bus cable connected to the subsequent
axis servo amplifier or with the termination connector MR-A-TM.
(j) Check that the encoder cable and servo motor power cable connected to the drive unit are connected
to the same servo motor properly.
(2) Axis number
(a) Check that the axis numbers of the servo system controller match the axis number settings of the
corresponding drive units.
(b) When changing the factory setting of any axis number (axis number slot number), check that the
IFU parameter No. 11 to 18 values are set without fail.
(c) Check that the encoder cable and motor power cable of the servo motor are wired to the drive unit
mounted to the slot as in the axis setting.
(3) Parameters
(a) Check that the drive unit parameters are set to correct values using the servo system controller
screen or MR Configurator (servo configuration software).
(b) Check that the interface unit parameters are set to correct values using the interface unit display
or MR Configurator (servo configuration software).
(4) Environment
Signal cables and power cables are not shorted by wire offcuts, metallic dust or the like.
(5) Machine
(a) The screws in the servo motor installation part and shaft-to-machine connection are tight.
(b) The servo motor and the machine connected with the servo motor can be operated.
